How do I record the data of a form in the database in Laravel 5.4?

I have a small problem in producing a registration system, everything is working fine, but when I check in the database no data submitted in the form appears, ie it is not registered.

Controller Class:

public function Submit(Request $request)
{
    Model::create($request ->all());
    return redirect()->action('MainController@index');
}        

Note: I do not go for View because it's too big ( has 150 lines of code, just the form, but if necessary I'll put it. )

Your respective model:

class Model extends Model
{
    protected $table = 'user';
    public $timestamps = false;

    protected $fillable = array('nome',
        'CPF',
        'email',
        'datnasc',
        'naturalidade',
        'turno',
        'uf_natural',
        'nome_mae',
        'nome_pai',
        'nome_resp',
        'cpf_resp',
        'rua',
        'numero',
        'bairro',
        'complemento',
        'cep',
        'didade',
        'estado',
        'tel_celular',
        'tel_fixo',
        'tipo_escola',
        'escola_origem',
        'serie');

    protected $guarded = ['id'];
}

How to solve this problem?
